Condemnation of Pride and Self-Conceit
وَعَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:"بَيْنَمَا رَجُلٌ يمشى فِي حُلَّةٍ تُعْجِبُهُ نَفْسُهُ، مُرَجِّلٌ رأسه، يختال في مشيته، إِذْ خَسَفَ اللَّهُ بِهِ، فَهْوَ يَتَجَلْجَلُ فِي الأَرْضِ إِلَى يَوْمِ الْقِيَامَةِ” ((مُتَّفَقٌ عَلَيْهِ)).
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "While a man was walking, dressed in clothes admiring himself, his hair combed, walking haughtily when Allah caused the earth to swallow him. Now he will continue to go down in it (as a punishment) until the Day of Resurrection." [Muslim].
